Here's why:
* Copyright Duration: Copyright on Wilde's works expired long ago. He died in 1900, and copyright generally lasts for the life of the author plus 70 years.
* Public Domain: Once a copyright expires, a work enters the public domain. This means anyone can use, copy, and distribute the work without needing permission.
However, there are a few things to keep in mind:
* Original Works vs. Quotes: While the quotes themselves are public domain, the original works from which they are taken may still be under copyright. This means you might need permission to reproduce the entire text of a story or play.
* Attribution: While you don't need permission to use Wilde's quotes, it's generally good practice to attribute the quote to him. This shows respect for the author and helps readers understand the source.
Example:
* Public Domain: "To live is the rarest thing in the world. Most people exist, that is all."
* Not Public Domain (may require permission): The entire text of "The Picture of Dorian Gray."
If you're unsure about the copyright status of a specific work, it's always best to err on the side of caution and seek legal advice.
